12. Time Step Adaptivity Controllers

The SUNDIALS library comes packaged with a variety of SUNAdaptController implementations, designed to support various forms of error-based time step adaptivity within SUNDIALS time integrators. To support applications that may want to adjust the controller parameters or provide their own implementations, SUNDIALS defines the SUNAdaptController base class, along with a variety of default implementations.
